Students and researchers in the health sciences are faced with greater opportunity and challenge than ever before. The opportunity stems from the explosion in publicly available data that simultaneously informs and inspires new avenues of investigation. The challenge is that the analytic tools required go far beyond the standard methods and models of basic statistics. This textbook aims to equip health care researchers with the most important elements of a modern health analytics toolkit, drawing from the fields of statistics, health econometrics, and data science. This textbook is designed to overcome students' anxiety about data and statistics and to help them to become confident users of appropriate analytic methods for health care research studies. Methods are presented organically, with new material building naturally on what has come before. Each technique is motivated by a topical research question, explained in non-technical terms, and accompanied by engaging explanations and examples. In this way, the authors cultivate a deep ("organic") understanding of a range of analytic techniques, their assumptions and data requirements, and their advantages and limitations. They illustrate all lessons via analyses of real data from a variety of publicly available databases, addressing relevant research questions and comparing findings to those of published studies. Ultimately, this textbook is designed to cultivate health services researchers that are thoughtful and well informed about health data science, rather than data analysts. This textbook differs from the competition in its unique blend of methods and its determination to ensure that readers gain an understanding of how, when, and why to apply them. It provides the public health researcher with a way to think analytically about scientific questions, and it offers well-founded guidance for pairing data with methods for valid analysis. Readers should feel emboldened to tackle analysis of real public datasets using traditional statistical models, health econometrics methods, and even predictive algorithms.

This book includes an international group of researchers who present the latest achievements in the field of enzyme, immune system, and microbial and nano-biosensors. It highlights the experimental evidence for formation of biological fuel cells (BFCs)-which has a dual purpose - as a device that produces electricity and the systems which produce it simultaneously cleaning up the environment from polluting organic compounds. Considering the work in the field of macro, micro and nano-biosensors, considerable attention is paid to the use of nanomaterials for the modification of working electrodes. Nanomaterials in some cases can significantly improve the parameters of analytical systems. Readers will be interested in the projection of the presented theoretical and experimental materials in the field of practical application of modern analytical developments. The presented results in many cases imply the possibility of using the created models of macro, micro and nano-biosensors, and biofuel elements in the field of health, and protection/restoration of the environment. It includes information about all existing types of transducers of signals in biosensors - electrochemical, optical and quantum-optics, thermoelectric, data of atomic force microscopy, piezoelectric, and more. On the basis of these principles, descriptions are given about the functioning of macro, micro and nano- biosensors for the detection of compounds used in medicine, detection of compounds that clog the environment, and thus affect human health, for compounds that are potentially the basis for the production of drugs, for the selection of compounds that have medicinal activity, for immunodetection, and to assess the quality of food. These questions form the basis of research carried out in the field of biosensors in the world. Since the described models of biosensors have high sensitivity, high measurement speed and selectivity, the described results attract the attention of both the ordinary reader and business class specialists who create and implement analytical technologies. This book is very useful for researchers in life sciences, chemical sciences, physics, and engineering. In addition, it will be useful for the persons working in industry. Advanced technologies specialists will be attracted by the novelty of the proposed solutions and their relevance and ease of implementation. Since the studies contain sections describing the parameters of different biosensors, BFCs, they are easily navigated into assessing the effectiveness of the practical use of the proposed device. The relevant sections indicate such characteristics as detection ranges, life span, type of biological material used, the method of formation of the bio-receptor part. These parameters are of interest to both developers of new models of biosensors and BFC, and their manufacturers.
X-ray diffraction is a useful and powerful analysis technique for characterizing crystalline materials commonly employed in MSE, physics, and chemistry. This informative new book describes the principles of X-ray diffraction and its applications to materials characterization. It consists of three parts. The first deals with elementary crystallography and optics, which is essential for understanding the theory of X-ray diffraction discussed in the second section of the book. Part 2 describes how the X-ray diffraction can be applied for characterizing such various forms of materials as thin films, single crystals, and powders. The third section of the book covers applications of X-ray diffraction. The book presents a number of examples to help readers better comprehend the subject. X-Ray Diffraction for Materials Research: From Fundamentals to Applications also * provides background knowledge of diffraction to enable nonspecialists to become familiar with the topics * covers the practical applications as well as the underlying principle of X-ray diffraction * presents appropriate examples with answers to help readers understand the contents more easily * includes thin film characterization by X-ray diffraction with relevant experimental techniques * presents a huge number of elaborately drawn graphics to help illustrate the content The book will help readers (students and researchers in materials science, physics, and chemistry) understand crystallography and crystal structures, interference and diffraction, structural analysis of bulk materials, characterization of thin films, and nondestructive measurement of internal stress and phase transition. Diffraction is an optical phenomenon and thus can be better understood when it is explained with an optical approach, which has been neglected in other books. This book helps to fill that gap, providing information to convey the concept of X-ray diffraction and how it can be applied to the materials analysis. This book will be a valuable reference book for researchers in the field and will work well as a good introductory book of X-ray diffraction for students in materials science, physics, and chemistry.
Soil is an important but often neglected element of the climate system. It is the second largest carbon store, or 'sink', after the oceans. Despite being a fundamental resource that supports all kinds of life on Earth, concerns related to soil are often not included as an important environmental issue. Climate changes put soil under pressure. The increasing concentration of carbon dioxide in our atmosphere may cause the microbes in the soil to work faster to break down organic matter, potentially releasing even more carbon dioxide. The soil moisture content is being constantly affected by rising temperatures and changes in precipitation patterns and future projections show that this may continue. This book presents current environmental issues and their remedies for soil which are mainly based on soil degradation, soil pollution and the effect of climate change on the soil. Adding xenobiotic chemicals or other alterations in the natural soil environment for agricultural, industrial or urban purposes result in a decline in the soil quality due to improper use or poor management, which is a serious environmental problem. The book is divided into five parts - soil science, soil physics, soil chemistry, soil biology and soil environment. The first part "Soil Science" serves as the introduction to the book and discusses some common topics such as soil formation, mineralogy, taxonomy, quality and analytical techniques. The second part "Soil Physics" is mainly concerned with the physical properties and processes of soil and their association with effects on air, water and temperature. Soil Chemistry, the third part, discusses the chemical reactions and processes between inorganic and organic components. The fourth part "Soil Biology" explains the biological properties and processes of the soil, with special concern to microbial diversity and its effect on the ecology. Lastly, the fifth part "Soil Environment" discusses the current environmental problems such as climate change and soil pollution, including processes to mitigate these issues through carbon sequestration, nutrient management and land management.

"Systems Biology of Apoptosis" summarizes all current achievements in this emerging field. Apoptosis is a process common to all multicellular organisms. Apoptosis leads to the elimination of cells via a complex but highly defined cellular programme. Defects in the regulation of apoptosis result in serious diseases such as cancer, autoimmunity, AIDS and neurodegeneration. Recently, a substantial step forward in understanding the complex apoptotic pathways has been made by utilising systems biology approaches. Systems biology combines rigorous mathematical modelling with experimental approaches in a closed loop cycle for advancing our knowledge about complex biological processes. In this book, the editor describes the contemporary systems biology studies devoted to apoptotic signaling and focuses on the question how systems biology helps to understand life/death decisions made in the cell and to develop new approaches to rational treatment strategies.

A New History of Vaccines for Infectious Diseases: Immunization - Chance and Necessity covers the developments of vaccines and how they have obliterated many fatal diseases and infections over time. The book treads a neutral path but does not avoid discussion. As uncertainty in the outcome of vaccination can only be determined by experiment, the path to vaccine development has been scientifically complex because the immune system and the manner in which humans respond to infection is variable and complex. Finally, the book describes the risks and benefits of vaccines in a visibly objective manner.
This book provides a compact introduction to the bootstrap method. In addition to classical results on point estimation and test theory, multivariate linear regression models and generalized linear models are covered in detail. Special attention is given to the use of bootstrap procedures to perform goodness-of-fit tests to validate model or distributional assumptions. In some cases, new methods are presented here for the first time. The text is motivated by practical examples and the implementations of the corresponding algorithms are always given directly in R in a comprehensible form. Overall, R is given great importance throughout. Each chapter includes a section of exercises and, for the more mathematically inclined readers, concludes with rigorous proofs. The intended audience is graduate students who already have a prior knowledge of probability theory and mathematical statistics.

Of the 7,000 estimated non-native species present in North America,
approximately 1,000 are invasive. Clearly, invasive species are in
the minority, but their small numbers don't keep them from causing
billions of dollars in economic and ecological harm each year.
Policymakers and ecologists continue to try to figure out which
species might be harmful, which invasive species are doing the most
damage, and which of these might respond best to eradication
efforts. Invasive species reports and case studies are prevalent in
political, environmental, and scientific news cycles, and a
significant portion of the public is concerned about the issue.
This book introduces advanced mathematical methods and techniques for analysis and simulation of models in mathematical epidemiology.

This book presents general theoretical tools as well as large number of specific examples to guide the reader to develop their own tools that they may then apply to study structured models in mathematical epidemiology. The book will be a valuable addition to the arsenal of all researchers interested in developing theory or studying specific models with age structure.
Johannes Klumpers Biotechnologies, such as genetic engineering, cloning and biodiversity, raise many legal and ethical concerns, so it is important that people understand these issues and feel able to express their opinions. This is why the European Commission has been, for a number of years, supporting actions to improve communication among scientists in these diverse areas. The project 'Women in Biotechnology' (WONBIT), financed under the 6th Framework programme of the European Commission, is an excellent example of what can be done to target opinion-formers such as scientists, economists and lawyers in bottom-up activities, and to encourage a debate on gender issues triggered by developments in the life sciences. WONBIT gave rise to a successful international conference highlighting the importance of adopting good practices and ethical considerations in parallel with the rapid pace of progress in biotechnology - from a woman's point of view. In particular, the conference addressed women in decision-making positions in b- technology with specific reference to scientific excellence, social competencies and management qualities as well as issues relating to environment, society and the younger generation. But it did not stop there: a key part of the conference was dedicated to stimulating public debate among non-specialists, which has led to a number of recommen- tions to policy-makers on better communication in biotechnology, on taking better account of the gender aspects of research, and on involving more women in the decision-making process that surrounds developments in biotechnology.

For some time, medicine has been an important driver for the development of data processing and visualization techniques. Improved technology offers the capacity to generate larger and more complex data sets related to imaging and simulation. This, in turn, creates the need for more effective visualization tools for medical practitioners to interpret and utilize data in meaningful ways. The first edition of Visualization in Medicine and Life Sciences (VMLS) emerged from a workshop convened to explore the significant data visualization challenges created by emerging technologies in the life sciences. The workshop and the book addressed questions of whether medical data visualization approaches can be devised or improved to meet these challenges, with the promise of ultimately being adopted by medical experts. Visualization in Medicine and Life Sciences II follows the second international VMLS workshop, held in Bremerhaven, Germany, in July 2009. Internationally renowned experts from the visualization and driving application areas came together for this second workshop. The book presents peer-reviewed research and survey papers which document and discuss the progress made, explore new approaches to data visualization, and assess new challenges and research directions. The assembled papers span the frontiers of VMLS, examining these topics: * Feature Extraction * Classification * Volumes and Shapes * Tensor Visualization * Visualizing Genes, Proteins, and Molecules" |
